Method for Applying a Liquid Composition to a Sanitary Tissue Product

ABSTRACT

Methods for applying a liquid composition to a sanitary tissue product and more particularly methods for applying a liquid composition from a source with a single activation by a user to deliver 100% of a user-desired precise amount of the liquid composition to a surface of a sanitary tissue product are provided.

FIELD OF THE INVENTION

The present invention relates to methods for applying a liquidcomposition, such as spraying a liquid composition, to a sanitary tissueproduct and more particularly to methods for applying a liquidcomposition, for example spraying a liquid composition, from a sourcewith a single activation by a user to deliver 100% of a user-desiredprecise amount of the liquid composition to a surface of a sanitarytissue product, for example a toilet tissue, a package comprising asanitary tissue product and a source of a liquid composition, such as acontainer or can, for example a spray device, containing the liquidcomposition, comprising a user-activated dispenser for dispensing in asingle activation 100% of a user-desired precise amount of the liquidcomposition, and a kit comprising a source of a liquid composition and apackage comprising one or more sanitary tissue products, wherein thesource comprises a user-activated dispenser for dispensing in a singleactivation 100% of a user-desired precise amount of the liquidcomposition.

BACKGROUND OF THE INVENTION

Methods for delivering a liquid composition to a surface of a sanitarytissue product are known. However, such known methods along with theiraccompanying devices (sources of the liquid composition) deliver apre-determined amount of the liquid composition to a surface of asanitary tissue product. For example, with a known device and method, amanufacturer-determined amount, for example a containermanufacturer-determined amount, is designed into the container such thata user has no freedom to adjust the amount of liquid compositiondelivered upon a single activation. Said another way, the known devicesand methods result in the user activating a source of a liquidcomposition and having to take what the user gets from the source of theliquid composition. Further, if the pre-determined amount is notsufficient with a single activation, then the user is required toactivate the source again, for example by depressing a dispensing buttonon the source to deliver yet another manufactured-determined amount ofthe liquid composition.

Such known devices and methods can be wasteful on one end and at aminimum annoying on the other end by the user not being able to achieve100% of a user-desired precise amount and/or a mess generated by thesource delivering an excessive amount of the liquid composition comparedto the user's desired amount.

The problem with known methods is that 100% of a user-desired preciseamount of a liquid composition cannot be delivered from a source, suchas a container.

Accordingly, there is a need for a novel method for applying 100% of auser-desired precise amount of a liquid composition to a sanitary tissueproduct in a single time with a single activation of a source of theliquid composition.

SUMMARY OF THE INVENTION

The present invention fulfills the need described above by providing amethod for applying, such as spraying, 100% of a user-desired preciseamount of a liquid composition to a sanitary tissue product in a singletime with a single activation of a source of the liquid composition.

The present invention provides a solution to the problem identifiedabove by providing a method for applying, for example spraying, 100% ofa user-desired precise amount of a liquid composition to a sanitarytissue product in a single time with a single activation of a source ofthe liquid composition.

a. providing a source of a liquid composition, for example a containeror can, such as a spray device, wherein the source comprises auser-activated dispenser for dispensing the liquid composition; and

b. activating the user-activated dispenser a single time to deliver 100%of a user-desired precise amount of the liquid composition to a surfaceof a sanitary tissue product is provided.

In another example of the present invention, a sanitary tissue productcomprising a liquid composition, wherein the sanitary tissue product isprepared by the method according to the present invention is provided.

In yet another example of the present invention, a package comprisingone or more sanitary tissue products and one or more sources of a liquidcomposition, for example one or more containers and/or cans, such as oneor more spray devices, wherein the source comprises a user-activateddispenser for dispensing in a single activation 100% of a user-desiredprecise amount of the liquid composition is provided.

In still another example of the present invention, a kit comprising asource of a liquid composition, for example a container and/or can, suchas a spray device, and a package comprising one or more sanitary tissueproducts, wherein the source comprises a user-activated dispenser fordispensing in a single activation 100% of a user-desired precise amountof the liquid composition, and optionally comprising instructions forapplying the liquid composition to the sanitary tissue product isprovided.

Accordingly, the present invention provides a novel method for applying,for example spraying, a liquid composition to a sanitary tissue product,a sanitary tissue product prepared from such method, a packagecomprising a sanitary tissue product and a source of a liquidcomposition, and a kit comprising a source of a liquid composition and apackage of a sanitary tissue product.

DETAILED DESCRIPTION OF THE INVENTION Definitions

“User-desired precise amount” as used herein means a user selectedand/or defined amount, no more and no less.

“Sanitary tissue product roll” as used herein means a roll of sanitarytissue product. The sanitary tissue product roll and thus the sanitarytissue product comprises a web convolutely wound, for example about acore, in the form of a roll. The core may comprise a wound andoverlapping tube of one or more layers comprised of paperboard or otherflexible materials, a wooden, metal, glass, plastic, or other compositematerial sleeve, or an extruded thermoplastic resin. The web may beadhered to the core or wound on the core without adhering to the core.The core may exhibit an outer diameter of less than 2.25 inches and/orless than 2.00 inches and/or less than 1.85 inches and/or less than 2.25inches to about 1.25 inches and/or less than 2.00 inches to about 1.50inches and/or less than 1.85 inches to about 1.50 inches. The web maycomprise one (a single-ply) or more (a multi-ply) fibrous structureplies, for example two or more fibrous structure plies and/or three ormore fibrous structure plies. Such sanitary tissue product rolls maycomprise a plurality of connected, but perforated sheets of sanitarytissue product (web) that are separably dispensable from adjacentsheets, for example via one or more perforations, for example aplurality of perforations within the sanitary tissue product (web). Theperforations in the sanitary tissue products of the present inventionmay be straight and/or shaped perforation lines examples of generalshapes of such perforation lines (areas or lines of weakness in thesanitary tissue product or web) are shown in FIG. 7 and may be extend inthe cross-machine direction (CD) and optionally, in the machinedirection (MD) and/or diagonally between the CD and MD.

“Sanitary tissue product”, which may be referred to herein as a “web”,as used herein means a soft, low density (i.e. <about 0.15 g/cm³)article comprising a web comprising one or more fibrous structure pliesaccording to the present invention, wherein the sanitary tissue productis useful as a wiping implement for post-urinary and post-bowel movementcleaning (toilet tissue), for otorhinolaryngological discharges (facialtissue), and multi-functional absorbent and cleaning uses (absorbenttowels).

In one example, the sanitary tissue product is a toilet tissue product(toilet tissue), for example a toilet tissue product that is designed tobe flushed down toilets, for example residential toilets, such astank-type toilets, and to disperse within municipal sewer systems and/orseptic systems/tanks. Such a toilet tissue product is void of permanentwet strength and/or levels of permanent wet strength agents, for examplepolyaminoamide-epichlorohydrin (PAE), which would negatively impact thetoilet tissue's decay such that the toilet tissue would exhibit a wetstrength decay of 25% or less, more typically a wet strength decay ofonly about 10-15% during a 30 minute soak test. Such a wet strengthdecay of 25% or less (typically 10-15%) is unacceptable and undesirablefor toilet tissue, which is designed to be flushed down toilets and intoseptic systems/tanks and/or municipal sewer systems. However, the toilettissue may comprise a temporary wet strength agent such that the toilettissue exhibits enough wet strength (temporary wet strength) to meetconsumer requirements (doesn't fall apart and/or disperse and/or leakthrough) during use, for example during the brief time the toilet tissueis wet during use and/or exposed to a relatively small amount of water(not saturated) by a consumer (during wiping, for example afterurinating), without causing the toilet tissue to exhibit flushabilityissues compared to the flushability issues a toilet tissue exhibitingpermanent wet strength would encounter. In one example, the toilettissue of the present invention exhibits a wet strength decay of greaterthan 60% during a 30 minute soak test (and typically even a wet strengthdecay of at least 40-60% after 2 minutes during the 30 minute soaktest), which is considered “temporary wet strength”, due to the concernsof flushability issues. Temporary wet strength in paper, for exampletoilet issue, is achieved by adding temporary wet strength agents, forexample glyoxylated polyacrylamide, to the toilet tissue.

In another example, the sanitary tissue product is a paper towel product(paper towel), for example a paper towel product designed to absorbfluids, such as water, while still remaining intact (not dispersing).Paper towel products are designed to not be flushed down toilets and/orto not disperse when wet. Such a paper towel product comprises permanentwet strength and/or levels of permanent wet strength agents, for examplepolyaminoamide-epichlorohydrin (PAE), which result in the paper towel'sexhibiting a wet strength decay of 25% or less, more typically a wetstrength decay of only about 10-15% during a 30 minute soak test.

Toilet tissue that exhibits temporary wet strength when disposed in atoilet due to the toilet bowl's water begins decaying, breaking apartinto pieces, and dispersing upon saturation of the toilet tissue. Papertowels, which exhibit permanent wet strength, are not suitable to beflushed in toilets because unlike toilet tissue, which exhibitstemporary wet strength, paper towels will not decay, break apart intopieces, and disperse upon saturation of the paper towel resulting in thetoilet being clogged and/or pipes, septic tank, and municipal sewersystems being “clogged” by the intact paper towel. One reason papertowels require permanent wet strength is that consumers may reuse andrewet a paper towel during use. As result of the issues associated withhaving permanent wet strength in toilet tissue (bath tissue), one ofordinary skill in the art understands that all bath tissue grades shouldnever include a level of permanent wet strength agent that would resultin the toilet tissue (bath tissue) exhibiting permanent wet strength andthus resulting in flushability issues, such as issues with dispersingand/or very low wet strength decay properties.

The sanitary tissue products of the present invention may exhibit abasis weight of greater than 15 g/m² to about 120 g/m² and/or from about15 g/m² to about 110 g/m² and/or from about 20 g/m² to about 100 g/m²and/or from about 30 to 90 g/m² as measured according to the respectiveBasis Weight Test Method described herein.

In one example, the sanitary tissue products,for example toilet tissue products, comprise a temporary wet strengthagent, for example a level of temporary wet strength agent, such thatthe sanitary tissue products exhibit the wet strength decay describedimmediately above.

“Web” and/or “fibrous structure” and/or “fibrous structure ply” as usedherein means a structure that comprises a plurality of pulp fibers. Inone example, the fibrous structure may comprise a plurality of wood pulpfibers. In another example, the fibrous structure may comprise aplurality of non-wood pulp fibers, for example plant fibers, syntheticstaple fibers, and mixtures thereof. In still another example, inaddition to pulp fibers, the fibrous structure may comprise a pluralityof filaments, such as polymeric filaments, for example thermoplasticfilaments such as polyolefin filaments (i.e., polypropylene filaments)and/or hydroxyl polymer filaments, for example polyvinyl alcoholfilaments and/or polysaccharide filaments such as starch filaments. Inone example, a fibrous structure according to the present inventionmeans an orderly arrangement of fibers alone and with filaments within astructure in order to perform a function. Non-limiting examples offibrous structures of the present invention include paper.

Non-limiting examples of processes for making fibrous structures includeknown wet-laid papermaking processes, for example conventionalwet-pressed papermaking processes and through-air-dried papermakingprocesses, and air-laid papermaking processes. Such processes typicallyinclude steps of preparing a fiber composition in the form of asuspension in a medium, either wet, more specifically aqueous medium, ordry, more specifically gaseous, i.e. with air as medium. The aqueousmedium used for wet-laid processes is oftentimes referred to as a fiberslurry. The fibrous slurry is then used to deposit a plurality of fibersonto a forming wire, fabric, or belt such that an embryonic fibrousstructure is formed, after which drying and/or bonding the fiberstogether results in a fibrous structure. Further processing the fibrousstructure may be carried out such that a finished fibrous structure isformed. For example, in typical papermaking processes, the finishedfibrous structure is the fibrous structure that is wound on the reel atthe end of papermaking, often referred to as a parent roll, and maysubsequently be converted into a finished product, e.g. a single- ormulti-ply sanitary tissue product.

The fibrous structures of the present invention may be homogeneous ormay be layered. If layered, the fibrous structures may comprise at leasttwo and/or at least three and/or at least four and/or at least fivelayers of fiber and/or filament compositions.

In one example, the fibrous structure of the present invention consistsessentially of fibers, for example pulp fibers, such as cellulosic pulpfibers and more particularly wood pulp fibers, such as 100% of thefibers present in the fibrous structure are pulp fibers, such ascellulosic pulp fibers and more particularly wood pulp fibers.

In another example, the fibrous structure of the present inventioncomprises fibers and is void of filaments.

In still another example, the fibrous structures of the presentinvention comprise filaments and fibers, such as a co-formed fibrousstructure.

“Co-formed fibrous structure” as used herein means that the fibrousstructure comprises a mixture of at least two different materialswherein at least one of the materials comprises a filament, such as apolypropylene filament, and at least one other material, different fromthe first material, comprises a solid additive, such as a fiber and/or aparticulate. In one example, a co-formed fibrous structure comprisessolid additives, such as fibers, such as wood pulp fibers, andfilaments, such as polypropylene filaments.

“Fiber” and/or “Filament” as used herein means an elongate particulatehaving an apparent length greatly exceeding its apparent width, i.e. alength to diameter ratio of at least about 10. In one example, a “fiber”is an elongate particulate as described above that exhibits a length ofless than 5.08 cm (2 in.) and a “filament” is an elongate particulate asdescribed above that exhibits a length of greater than or equal to 5.08cm (2 in.).

Fibers are typically considered discontinuous in nature. Non-limitingexamples of fibers include pulp fibers, such as wood pulp fibers, andsynthetic staple fibers such as polyester fibers.

Filaments are typically considered continuous or substantiallycontinuous in nature. Filaments are relatively longer than fibers.Non-limiting examples of filaments include meltblown and/or spunbondfilaments. Non-limiting examples of materials that can be spun intofilaments include natural polymers, such as starch, starch derivatives,cellulose and cellulose derivatives, hemicellulose, hemicellulosederivatives, and synthetic polymers including, but not limited topolyvinyl alcohol filaments and/or polyvinyl alcohol derivativefilaments, and thermoplastic polymer filaments, such as polyesters,nylons, polyolefins such as polypropylene filaments, polyethylenefilaments, and biodegradable or compostable thermoplastic fibers such aspolylactic acid filaments, polyhydroxyalkanoate filaments andpolycaprolactone filaments. The filaments may be monocomponent ormulticomponent, such as bicomponent filaments.

In one example of the present invention, “fiber” refers to papermakingfibers. Papermaking fibers useful in the present invention includecellulosic fibers commonly known as wood pulp fibers. Applicable woodpulps include chemical pulps, such as Kraft, sulfite, and sulfate pulps,as well as mechanical pulps including, for example, groundwood,thermomechanical pulp and chemically modified thermomechanical pulp.Chemical pulps, however, may be preferred since they impart a superiortactile sense of softness to tissue sheets made therefrom. Pulps derivedfrom both deciduous trees (hereinafter, also referred to as “hardwood”)and coniferous trees (hereinafter, also referred to as “softwood”) maybe utilized. The hardwood and softwood fibers can be blended, oralternatively, can be deposited in layers to provide a stratifiedfibrous structure. U.S. Pat. Nos. 4,300,981 and 3,994,771 areincorporated herein by reference for the purpose of disclosing layeringof hardwood and softwood fibers. Also applicable to the presentinvention are fibers derived from recycled paper, which may contain anyor all of the above categories as well as other non-fibrous materialssuch as fillers and adhesives used to facilitate the originalpapermaking.

In one example, the wood pulp fibers are selected from the groupconsisting of hardwood pulp fibers, softwood pulp fibers, and mixturesthereof. The hardwood pulp fibers may be selected from the groupconsisting of: tropical hardwood pulp fibers, northern hardwood pulpfibers, and mixtures thereof. The tropical hardwood pulp fibers may beselected from the group consisting of: eucalyptus fibers, acacia fibers,and mixtures thereof. The northern hardwood pulp fibers may be selectedfrom the group consisting of: cedar fibers, maple fibers, and mixturesthereof.

In addition to the various wood pulp fibers, other cellulosic fiberssuch as cotton linters, rayon, lyocell, trichomes, seed hairs, andbagasse can be used in this invention. Other sources of cellulose in theform of fibers or capable of being spun into fibers include grasses andgrain sources.

“Trichome” or “trichome fiber” as used herein means an epidermalattachment of a varying shape, structure and/or function of a non-seedportion of a plant. In one example, a trichome is an outgrowth of theepidermis of a non-seed portion of a plant. The outgrowth may extendfrom an epidermal cell. In one embodiment, the outgrowth is a trichomefiber. The outgrowth may be a hairlike or bristlelike outgrowth from theepidermis of a plant.

Trichome fibers are different from seed hair fibers in that they are notattached to seed portions of a plant. For example, trichome fibers,unlike seed hair fibers, are not attached to a seed or a seed podepidermis. Cotton, kapok, milkweed, and coconut coir are non-limitingexamples of seed hair fibers.

Further, trichome fibers are different from nonwood bast and/or corefibers in that they are not attached to the bast, also known as phloem,or the core, also known as xylem portions of a nonwood dicotyledonousplant stem. Non-limiting examples of plants which have been used toyield nonwood bast fibers and/or nonwood core fibers include kenaf,jute, flax, ramie and hemp.

Further trichome fibers are different from monocotyledonous plantderived fibers such as those derived from cereal straws (wheat, rye,barley, oat, etc.), stalks (corn, cotton, sorghum, Hesperaloe funifera,etc.), canes (bamboo, bagasse, etc.), grasses (esparto, lemon, sabai,switchgrass, etc), since such monocotyledonous plant derived fibers arenot attached to an epidermis of a plant.

Further, trichome fibers are different from leaf fibers in that they donot originate from within the leaf structure. Sisal and abaca aresometimes liberated as leaf fibers.

Finally, trichome fibers are different from wood pulp fibers since woodpulp fibers are not outgrowths from the epidermis of a plant; namely, atree. Wood pulp fibers rather originate from the secondary xylem portionof the tree stem.

“Basis Weight” as used herein is the weight per unit area of a samplereported in lbs/3000 ft² or g/m² (gsm) and is measured according to therespective Basis Weight Test Method described herein.

“Machine Direction” or “MD” as used herein means the direction parallelto the flow of the fibrous structure through the web (fibrous structure)making machine and/or sanitary tissue product manufacturing equipment.

“Cross Machine Direction” or “CD” as used herein means the directionparallel to the width of the web (fibrous structure) making machineand/or sanitary tissue product manufacturing equipment and perpendicularto the machine direction.

“Ply” as used herein means an individual, integral web (fibrousstructure).

“Plies” as used herein means two or more individual, integral webs(fibrous structures) disposed in a substantially contiguous,face-to-face relationship with one another, forming a multi-ply fibrousstructure and/or multi-ply sanitary tissue product. It is alsocontemplated that an individual, integral web (fibrous structure) caneffectively form a multi-ply fibrous structure, for example, by beingfolded on itself.

“Embossed” as used herein with respect to a web and/or sanitary tissueproduct means that a web and/or sanitary tissue product of the presentinvention has been subjected to a process which converts a smoothsurfaced web and/or sanitary tissue product to a decorative surface byreplicating a design on one or more emboss rolls, which form a nipthrough which the web and/or sanitary tissue product passes. Embosseddoes not include creping, microcreping, printing or other processes thatmay also impart a texture and/or decorative pattern to a web and/orsanitary tissue product.

“Differential density”, as used herein, means a web and/or sanitarytissue product of the present invention that comprises one or moreregions of relatively low fiber density, which are referred to as pillowregions, and one or more regions of relatively high fiber density, whichare referred to as knuckle regions.

“Densified”, as used herein means a portion of a web and/or sanitarytissue product of the present invention that is characterized by regionsof relatively high fiber density (knuckle regions).

“Non-densified”, as used herein, means a portion of a web and/orsanitary tissue product of the present invention that exhibits a lesserdensity (one or more regions of relatively lower fiber density) (pillowregions) than another portion (for example a knuckle region) of the weband/or sanitary tissue product.

“Creped” as used herein means creped off of a Yankee dryer or othersimilar roll and/or fabric creped and/or belt creped. Rush transfer of aweb (fibrous structure) alone does not result in a “creped” fibrousstructure or “creped” sanitary tissue product for purposes of thepresent invention.

“Container” and/or “Can” as used herein means a vessel that is intendedto store and dispense a liquid composition, for example in a sprayand/or aerosol form. In one example, a container comprises a reservoirfor storing the liquid composition and a user-activated dispenser, forexample an actuator. One example a of suitable container and/or can is aspray device, such as an aerosol can.

“Aerosol can” and/or “Aerosol spray device” as used herein means acontainer and/or can that uses a propellant to pressurize the liquidcomposition and/or atomize the liquid composition when dispensed, forexample sprayed, from the container and/or can.

“Propellant” as used herein means one or more gases that are used topressurize the liquid composition to facilitate egress of the liquidcomposition from a source of the liquid composition, for example from acontainer and/or can, such as a spray device and/or aerosol cancontaining the liquid composition. Some propellants may be a mixture ofgases (e.g. A-46, which is a mixture of isobutane, butane, and propane).In one example, a propellant is in the form of a liquid (i.e., aliquified gas) when under pressure within a container and/or can. Inanother example, a propellant is in the form of a gas or mixture ofgases in its/their gaseous state within the head space of a reservoirwithin a container and/or can containing a liquid composition. Inanother example, a propellant may be present in both a liquified formand its gaseous state within the reservoir of the container and/or can.

Non-Limiting Example of Method for Making Sanitary Tissue Product

The following Example illustrates a non-limiting example for apreparation of a sanitary tissue product roll comprising a webcomprising a fibrous structure ply according to the present inventionmade on a pilot-scale Fourdrinier fibrous structure making (papermaking)machine.

An aqueous slurry of eucalyptus (Suzano, formerly Fibria, Brazilianbleached hardwood kraft pulp) pulp fibers is prepared at about 3% fiberby weight using a conventional repulper, then transferred to thehardwood fiber stock chest. The eucalyptus fiber slurry of the hardwoodstock chest is pumped through a stock pipe to a hardwood fan pump wherethe slurry consistency is reduced from about 3% by fiber weight to about0.15% by fiber weight. The 0.15% eucalyptus slurry is then pumped andequally distributed in the top and bottom chambers of a multi-layered,three-chambered headbox of a Fourdrinier wet-laid papermaking machine.

Additionally, an aqueous slurry of NSK (Northern Softwood Kraft) pulpfibers is prepared at about 3% fiber by weight using a conventionalrepulper, then transferred to the softwood fiber stock chest. The NSKfiber slurry of the softwood stock chest is pumped through a stock pipeto be refined to a Canadian Standard Freeness (CSF) of about 630. Therefined NSK fiber slurry is then directed to the NSK fan pump where theNSK slurry consistency is reduced from about 3% by fiber weight to about0.15% by fiber weight. The 0.15% eucalyptus slurry is then directed anddistributed to the center chamber of a multi-layered, three-chamberedheadbox of a Fourdrinier wet-laid papermaking machine.

The wet-laid papermaking machine has a layered headbox having a topchamber, a center chamber, and a bottom chamber where the chambers feeddirectly onto the forming wire (Fourdrinier wire). The eucalyptus fiberslurry of 0.15% consistency is directed to the top headbox chamber andbottom headbox chamber. The NSK fiber slurry is directed to the centerheadbox chamber. All three fiber layers are delivered simultaneously insuperposed relation onto the Fourdrinier wire to form thereon athree-layer embryonic fibrous structure (web), of which about 38% of thetop side is made up of the eucalyptus fibers, about 38% is made of theeucalyptus fibers on the bottom side and about 24% is made up of the NSKfibers in the center. Dewatering occurs through the Fourdrinier wire andis assisted by a deflector and wire table vacuum boxes. The Fourdrinierwire is an 84M (84 by 76 5A, Albany International). The speed of theFourdrinier wire is about 750 feet per minute (fpm).

The embryonic wet fibrous structure is transferred from the Fourdrinierwire, at a fiber consistency of about 15% at the point of transfer, to a3D patterned through-air-drying belt. The speed of the 3D patternedthrough-air-drying belt is the same as the speed of the Fourdrinierwire. The 3D patterned through-air-drying belt is designed to yield afibrous structure comprising a pattern of high density knuckle regionsdispersed throughout a multi-elevational continuous pillow region. Themulti-elevational continuous pillow region comprises an intermediatedensity pillow region (density between the high density knuckles and thelow density other pillow region) and a low density pillow region formedby the deflection conduits created by the semi-continuous knuckle layersubstantially oriented in the machine direction. The supporting fabricof the 3D patterned through-air-drying belt is a 98×52 filament, duallayer fine mesh. The thickness of the first layer resin cast of the beltis about 6 mils above the supporting fabric and the thickness of thesecond layer resin cast of the belt is about 13 mils above thesupporting fabric.

Further de-watering of the fibrous structure is accomplished by vacuumassisted drainage until the fibrous structure has a fiber consistency ofabout 20% to 30%.

While remaining in contact with the 3D patterned through-air-dryingbelt, the fibrous structure is pre-dried by air blow-through pre-dryersto a fiber consistency of about 53% by weight.

After the pre-dryers, the semi-dry fibrous structure is transferred to aYankee dryer and adhered to the surface of the Yankee dryer with asprayed creping adhesive. The creping adhesive is an aqueous dispersionwith the actives consisting of about 80% polyvinyl alcohol (PVA 88-50),about 20% CREPETROL® 457T20. CREPETROL® 457T20 is commercially availablefrom Hercules Incorporated of Wilmington, Del. The creping adhesive isdelivered to the Yankee surface at a rate of about 0.15% adhesive solidsbased on the dry weight of the fibrous structure. The fiber consistencyis increased to about 97% before the fibrous structure is dry-crepedfrom the Yankee with a doctor blade.

The doctor blade has a bevel angle of about 25° and is positioned withrespect to the Yankee dryer to provide an impact angle of about 81°. TheYankee dryer is operated at a temperature of about 275° F. and a speedof about 800 fpm. The fibrous structure is wound in a roll (parent roll)using a surface driven reel drum having a surface speed of about 757fpm.

Method for Applying a Liquid Composition to a Sanitary Tissue Product

As shown in FIG. 1, an example of a method 10 for applying a liquidcomposition 12 to a sanitary tissue product 14 according to the presentinvention comprises the steps of:

a. providing a source 16, for example a can, such as an aerosol can, forexample a hand held can, of a liquid composition, wherein the source 16comprises a user-activated dispenser 18 for dispensing the liquidcomposition 12; and

b. activating the user-activated dispenser 18, for example a usercontacts and depresses the user-activated dispenser 18 with a user'sfinger 20, a single time to deliver 100% of a user-desired preciseamount of the liquid composition 12 to a surface 22 of a sanitary tissueproduct 14.

The user activates the user-activated dispenser 18 a single time as asingle activation until 100% of the user-desired precise amount isdelivered to the surface 22 of the sanitary tissue product 14 at whichtime the user ceases activating (“deactivates”) the user-activateddispenser 18 causing the liquid composition 12 to stop exiting thesource 16 of the liquid composition 12 through the user-activateddispenser 18. The user desires no less and no more than 100% of theuser-desired precise amount to be delivered to the user's sanitarytissue product 14.

In one example, the step of activating the user-activated dispenserfurther comprises the step of the user moving the source of the liquidcomposition during delivery of the liquid composition to the surface ofthe sanitary tissue product.

In another example, the step of activating the user-activated dispenserfurther comprises the step of the user moving the sanitary tissueproduct during delivery of the liquid composition to the surface of thesanitary tissue product.

Source of Liquid Composition

The source of liquid composition may be any suitable source that issuitable for delivering (applying) 100% of a user-desired precise amountof the liquid to a sanitary tissue product.

Like inthe case of an aerosol can, the source of the liquid composition maycomprise a propellant to aid in the dispensing of the liquid compositionfrom the source of the liquid composition.

In one example, the source of the liquid composition, for example acontainer and/or can, comprises a user-activated dispenser fordispensing the liquid composition. In one example, the sourcecontinuously dispenses the liquid composition until the user deactivatesthe user-activated dispenser, for example once 100% of the user-desiredprecise amount of liquid composition has been delivered/applied to asurface of the user's sanitary tissue product. In such a case, the userdoes not have to repeated press and/or pump the dispenser to achievedelivery and/or application of the liquid composition from the source ofthe liquid composition.

Basis Weight Test Method for Toilet Tissue Samples

Basis weight of a fibrous structure and/or sanitary tissue product ismeasured on stacks of twelve usable units using a top loading analyticalbalance with a resolution of ±0.001 g. The balance is protected from airdrafts and other disturbances using a draft shield. A precision cuttingdie, measuring 3.500 in ±0.007 in by 3.500 in ±0.007 in is used toprepare all samples.

Stack six usable units aligning any perforations or folds on the sameside of stack. With a precision cutting die, cut the stack into squares.Select six more usable units of the sample; stack and cut in like mannerCombine the two stacks to form a single stack twelve squares thick.Measure the mass of the sample stack and record the result to thenearest 0.001 g.

The Basis Weight is calculated in lbs/3000 ft² or g/m² as follows:

Basis Weight=(Mass of stack)/[(Area of 1 layer in stack)×(Number oflayers)]

For example,

Basis Weight (lbs/3000 ft²)=[[Mass of stack (g)/453.6 (g/lbs)]/[12.25(in²)/144 (in²/ft²)×12]]×3000

Or,

Basis Weight (g/m²)=Mass of stack (g)/[79.032 (cm²)/10,000 (cm²/m²)×12]

Report result to the nearest 0.1 lbs/3000 ft² or 0.1 g/m². Sampledimensions can be changed or varied using a similar precision cutter asmentioned above, so as at least 100 square inches of sample area instack.

Basis weight of a fibrous structure and/or sanitary tissue product ismeasured on stacks of twelve usable units using a top loading analyticalbalance with a resolution of ±0.001 g. The balance is protected from airdrafts and other disturbances using a draft shield. A precision cuttingdie, measuring 4.000 in ±0.008 in by 4.000 in ±0.008 in is used toprepare all samples.

Stack eight usable units aligning any perforations or folds on the sameside of stack. With a precision cutting die, cut the stack into squares.Measure the mass of the sample stack and record the result to thenearest 0.001 g.

The Basis Weight is calculated in lbs/3000 ft² or g/m² as follows:

Basis Weight=(Mass of stack)/[(Area of 1 layer in stack)×(Number oflayers)]

For example,

Basis Weight (lbs/3000 ft²)=[[Mass of stack (g)/453.6 (g/lbs)]/[16(in²)/144 (in²/ft²)×8]]×3000

Or,

Report result to the nearest 0.1 lbs/3000 ft² or 0.1 g/m². Sampledimensions can be changed or varied using a similar precision cutter asmentioned above, so as at least 100 square inches of sample area instack.

Caliper Test Method

Caliper of a sanitary tissue product or web is measured using a ProGageThickness Tester (Thwing-Albert Instrument Company, West Berlin, N.J.)with a pressure foot diameter of 2.00 inches (area of 3.14 in²) at apressure of 95 g/in². Four (4) samples are prepared by cutting of ausable unit such that each cut sample is at least 2.5 inches per side,avoiding creases, folds, and obvious defects. An individual specimen isplaced on the anvil with the specimen centered underneath the pressurefoot. The foot is lowered at 0.03 in/sec to an applied pressure of 95g/in². The reading is taken after 3 sec dwell time, and the foot israised. The measure is repeated in like fashion for the remaining 3specimens. The caliper is calculated as the average caliper of the fourspecimens and is reported in mils (0.001 in) to the nearest 0.1 mils.

Dry Tensile Strength Test Method for Toilet Tissue Samples

Elongation, Tensile Strength, TEA and Tangent Modulus are measured on aconstant rate of extension tensile tester with computer interface (asuitable instrument is the EJA Vantage from the Thwing-Albert InstrumentCo. Wet Berlin, N.J.) using a load cell for which the forces measuredare within 10% to 90% of the limit of the load cell. Both the movable(upper) and stationary (lower) pneumatic jaws are fitted with smoothstainless steel faced grips, with a design suitable for testing 1 inchwide sheet material (Thwing-Albert item #733GC). An air pressure ofabout 60 psi is supplied to the jaws.

Twenty usable units of sanitary tissue product or web are divided intofour stacks of five usable units each. The usable units in each stackare consistently oriented with respect to machine direction (MD) andcross direction (CD). Two of the stacks are designated for testing inthe MD and two for CD. Using a one inch precision cutter (Thwing Albert)take a CD stack and cut two, 1.00 in ±0.01 in wide by at least 3.0 inlong strips from each CD stack (long dimension in CD). Each strip isfive usable unit layers thick and will be treated as a unitary specimenfor testing. In like fashion cut the remaining CD stack and the two MDstacks (long dimension in MD) to give a total of 8 specimens (fivelayers each), four CD and four MD.

Program the tensile tester to perform an extension test, collectingforce and extension data at an acquisition rate of 20 Hz as thecrosshead raises at a rate of 4.00 in/min (10.16 cm/min) until thespecimen breaks. The break sensitivity is set to 50%, i.e., the test isterminated when the measured force drops to 50% of the maximum peakforce, after which the crosshead is returned to its original position.

Set the gage length to 2.00 inches. Zero the crosshead and load cell.Insert the specimen into the upper and lower open grips such that atleast 0.5 inches of specimen length is contained each grip. Alignspecimen vertically within the upper and lower jaws, then close theupper grip. Verify specimen is aligned, then close lower grip. Thespecimen should be under enough tension to eliminate any slack, but lessthan 0.05 N of force measured on the load cell. Start the tensile testerand data collection. Repeat testing in like fashion for all four CD andfour MD specimens.

Program the software to calculate the following from the constructedforce (g) verses extension (in) curve:

Tensile Strength is the maximum peak force (g) divided by the product ofthe specimen width (1 in) and the number of usable units in the specimen(5), and then reported as Win to the nearest 1 g/in.

Adjusted Gage Length is calculated as the extension measured at 11.12 gof force (in) added to the original gage length (in).

Elongation is calculated as the extension at maximum peak force (in)divided by the Adjusted Gage Length (in) multiplied by 100 and reportedas % to the nearest 0.1%.

Tensile Energy Absorption (TEA) is calculated as the area under theforce curve integrated from zero extension to the extension at themaximum peak force (g*in), divided by the product of the adjusted GageLength (in), specimen width (in), and number of usable units in thespecimen (5). This is reported as g*in/in² to the nearest 1 g*in/in².

Dry Tensile Strength Test Method for Paper Towel Samples

Elongation, Tensile Strength, TEA and Tangent Modulus are measured on aconstant rate of extension tensile tester with computer interface (asuitable instrument is the EJA Vantage from the Thwing-Albert InstrumentCo. Wet Berlin, N.J.) using a load cell for which the forces measuredare within 10% to 90% of the limit of the load cell. Both the movable(upper) and stationary (lower) pneumatic jaws are fitted with smoothstainless steel faced grips, with a design suitable for testing 1 inchwide sheet material (Thwing-Albert item #733GC). An air pressure ofabout 60 psi is supplied to the jaws.

Eight usable units of sanitary tissue product or web are divided intotwo stacks of four usable units each. The usable units in each stack areconsistently oriented with respect to machine direction (MD) and crossdirection (CD). One of the stacks is designated for testing in the MDand the other for CD. Using a one inch precision cutter (Thwing Albert)take a CD stack and cut one, 1.00 in ±0.01 in wide by at least 5.0 inlong stack of strips (long dimension in CD). In like fashion cut theremaining stack in the MD (strip long dimension in MD), to give a totalof 8 specimens, four CD and four MD strips. Each strip to be tested isone usable unit thick and will be treated as a unitary specimen fortesting.

Program the tensile tester to perform an extension test, collectingforce and extension data at an acquisition rate of 20 Hz as thecrosshead raises at a rate of 4.00 in/min (10.16 cm/min) until thespecimen breaks. The break sensitivity is set to 50%, i.e., the test isterminated when the measured force drops to 50% of the maximum peakforce, after which the crosshead is returned to its original position.

Set the gage length to 4.00 inches. Zero the crosshead and load cell.Insert the specimen into the upper and lower open grips such that atleast 0.5 inches of specimen length is contained each grip. Alignspecimen vertically within the upper and lower jaws, then close theupper grip. Verify specimen is aligned, then close lower grip. Thespecimen should be under enough tension to eliminate any slack, but lessthan 0.05 N of force measured on the load cell. Start the tensile testerand data collection. Repeat testing in like fashion for all four CD andfour MD specimens.

Program the software to calculate the following from the constructedforce (g) verses extension (in) curve:

Tensile Strength is the maximum peak force (g) divided by the specimenwidth (1 in), and reported as Win to the nearest 1 Win.

Adjusted Gage Length is calculated as the extension measured at 11.12 gof force (in) added to the original gage length (in).

Elongation is calculated as the extension at maximum peak force (in)divided by the Adjusted Gage Length (in) multiplied by 100 and reportedas % to the nearest 0.1%.

Tensile Energy Absorption (TEA) is calculated as the area under theforce curve integrated from zero extension to the extension at themaximum peak force (g*in), divided by the product of the adjusted GageLength (in) and specimen width (in). This is reported as g*in/in² to thenearest 1 g*in/in².

Wet Tensile Test Method

The Wet Tensile Strength test method is utilized for the determinationof the wet tensile strength of a sanitary tissue product or web stripafter soaking with water, using a tensile-strength-testing apparatusoperating with a constant rate of elongation. The Wet Tensile Strengthtest is run according to ISO 12625-5:2005, except for any deviations ormodifications described below. This method uses a verticaltensile-strength tester, in which a device that is held in the lowergrip of the tensile-strength tester, called a Finch Cup, is used toachieve the wetting.

Using a one inch JDC precision sample cutter (Thwing Albert) cut six1.00 in ±0.01 in wide strips from a sanitary tissue product sheet or websheet in the machine direction (MD), and six strips in the cross machinedirection (CD). An electronic tensile tester (Model 1122, Instron Corp.,or equivalent) is used and operated at a crosshead speed of 1.0 inch(about 1.3 cm) per minute and a gauge length of 1.0 inch (about 2.5 cm).The two ends of the strip are placed in the upper jaws of the machine,and the center of the strip is placed around a stainless steel peg. Thestrip is soaked in distilled water at about 20° C. for the identifiedsoak time, and then measured for peak tensile strength. Reference to amachine direction means that the sample being tested is prepared suchthat the length of the strip is cut parallel to the machine direction ofmanufacture of the product.

The MD and CD wet peak tensile strengths are determined using the aboveequipment and calculations in the conventional manner. The reportedvalue is the arithmetic average of the six strips tested for eachdirectional strength to the nearest 0.1 grams force. The total wettensile strength for a given soak time is the arithmetic total of the MDand CD tensile strengths for that soak time. Initial total wet tensilestrength (“ITWT”) is measured when the paper has been submerged for5±0.5 seconds. Decayed total wet tensile (“DTWT”) is measured after thepaper has been submerged for 30±0.5 minutes.

Wet Decay Test Method

Wet decay (loss of wet tensile) for a sanitary tissue product or web ismeasured according to the Wet Tensile Test Method described herein andis the wet tensile of the sanitary tissue product or web after it hasbeen standing in the soaked condition in the Finch Cup for 30 minutes.Wet decay is reported in units of “%”. Wet decay is the % loss ofInitial Total Wet Tensile after the 30 minute soaking.

Dry Burst Test Method

The Dry Burst Test is run according to ISO 12625-9:2005, except for anydeviations described below. Sanitary tissue product samples or websamples for each condition to be tested are cut to a size appropriatefor testing, a minimum of five (5) samples for each condition to betested are prepared.

A burst tester (Burst Tester Intelect-II-STD Tensile Test Instrument,Cat. No. 1451-24PGB available from Thwing-Albert Instrument Co.,Philadelphia, Pa., or equivalent) is set up according to themanufacturer's instructions and the following conditions: Speed: 12.7centimeters per minute; Break Sensitivity: 20 grams; and Peak Load: 2000grams. The load cell is calibrated according to the expected burststrength.

A sanitary tissue product sample or web sample to be tested is clampedand held between the annular clamps of the burst tester and is subjectedto increasing force that is applied by a 0.625 inch diameter, polishedstainless steel ball upon operation of the burst tester according to themanufacturer's instructions. The burst strength is that force thatcauses the sample to fail.

The burst strength for each sanitary tissue product sample or web sampleis recorded. An average and a standard deviation for the burst strengthfor each condition is calculated.

The Dry Burst is reported as the average and standard deviation for eachcondition to the nearest gram.

Wet Burst Test Method

“Wet Burst Strength” as used herein is a measure of the ability of asanitary tissue product or web to absorb energy, when wet and subjectedto deformation normal to the plane of the sanitary tissue product orweb. The Wet Burst Test is run according to ISO 12625-9:2005, except forany deviations or modifications described below.

Wet burst strength may be measured using a Thwing-Albert Burst TesterCat. No. 177 equipped with a 2000 g load cell commercially availablefrom Thwing-Albert Instrument Company, Philadelphia, Pa., or anequivalent instrument.

Wet burst strength is measured by preparing four (4) sanitary tissueproduct samples or web samples for testing. First, condition the samplesfor two (2) hours at a temperature of 73° F.±2° F. (23° C.±1° C.) and arelative humidity of 50% (±2%). Take one sample and horizontally dip thecenter of the sample into a pan filled with about 25 mm of roomtemperature distilled water. Leave the sample in the water four (4)(±0.5) seconds. Remove and drain for three (3) (±0.5) seconds holdingthe sample vertically so the water runs off in the cross machinedirection. Proceed with the test immediately after the drain step.

Place the wet sample on the lower ring of the sample holding device ofthe Burst Tester with the outer surface of the sample facing up so thatthe wet part of the sample completely covers the open surface of thesample holding ring. If wrinkles are present, discard the samples andrepeat with a new sample. After the sample is properly in place on thelower sample holding ring, turn the switch that lowers the upper ring onthe Burst Tester. The sample to be tested is now securely gripped in thesample holding unit. Start the burst test immediately at this point bypressing the start button on the Burst Tester. A plunger will begin torise (or lower) toward the wet surface of the sample. At the point whenthe sample tears or ruptures, report the maximum reading. The plungerwill automatically reverse and return to its original starting position.Repeat this procedure on three (3) more samples for a total of four (4)tests, i.e., four (4) replicates. Report the results as an average ofthe four (4) replicates, to the nearest gram.

Measurements are taken attrajectory analysis points using the RTSizer software (or equivalent)and derived data is displayed, and printed.

To set the trajectory analysis points, do the following:

Ensure that the can (aerosol can) is positioned adjacent to the laserbeam and 6″ from the center of the laser beam such that the spray plumetrajectory from the can intersects the laser beam at 90° and such thatthe spray plume trajectory lies in the same horizontal plane as laserbeam (Slightly offset downward such that the center of the spray conepattern is −0.25° in the y-axis (below the vertical center of the laserbeam) to achieve optimal spray cone pattern, for example upper ⅓ ofspray cone pattern, and oriented on the x-axis to achieve optimal x-axisdistance along the laser beam from the receiver lens to prevent receivelens saturation. The orientation device holding the can (aerosol can)may be adjusted in its x-axis, y-axis, and z-axis to achieve that theactuator spray path is located perpendicular to the laser beam (offset yand z axes from vertical center of laser beam when necessary to preventlens saturation and attain the upper ⅓ of spray cone pattern beinganalyzed). Use a ruler to check orientation and correct trajectoryanalysis point locations.
